Touchscreen smart monitors introducing interaction to the classroom

Among the fixtures of classrooms conjured up when on imagines schooling – tables and chairs, lockers for books and hooks for coats, the teacher’s desk and bunting for juvenile art – few are as storied as the blackboard. This surface has been a vector for learning, through the medium of chalk, since the 1500s, and has been romanticised on film by Sydney Poitier, in song by Hank Thompson and on television by The Simpsons.
